Let us remember what the psalmist David wrote: “Because thou wilt not leave my soul in hell [Latin, infernus]; nor wilt thou give thy holy one to see corruption.” (Ps. 15:10, Douay; Ps 16:10, Authorized Version) Was David here speaking about himself? The Christian apostle Peter says No. On the day of Pentecost of the year 33 C.E., Peter quoted this psalm of David and applied it to the right one.

Whereas therefore he was a prophet, and knew that God hath sworn to him with an oath, that of the fruit of his loins one should sit upon his throne.
